Bel Digital Audio has added a loudness monitoring option to the latest standards on all eight variants of its 1U and 2U 16-channel HD monitor/de-embedder. Each of the monitors now has the ability to choose between monitoring loudness by momentary, 3s, 10s, integrated and dynamic ranges. As a consequence, all units comply with both ITU-R BS.1770-2 and ITU-R BS.1771-1.
Loudness metering can be displayed in four ways, chosen from the easily navigated menu, with each showing different combinations of loudness measures. This enables the user to choose which measurements they prefer to show more prominently. The units are configured quickly via a rotary control that scrolls through menu options and settings. The menu system need only be accessed once during set-up, and from that point forward all the required options will be displayed. Loudness metering is accessed through the same intuitive system and each of the four monitoring options can be displayed permanently or called up as required.
Visible monitoring of each channel of audio is by high-resolution bargraph meters, with adjustable colour transition points featuring a peak-hold facility. Four user assignable scales and ballistics are also available. Audible monitoring is via magnetically shielded speakers.
All units feature medical grade internal power supplies for reliability, whilst also removing the need for any external power adapters. There is also the facility for SDI re-clocking and loop-through on each device.
